After all of the seven got married and had kids, (we're gonna pretend Jason wasn't stabbed by a ancient roman emperor), they all went to Salt Lake City, Utah. Their kids where so confused as to why they were staying on an island in the middle of the lake and they weren't in the city. Their parents just laughed and said there was a long story behind it. Then Percy and Annabeth's oldest daughter Selena, and Piper and Jason's oldest son, Robert, liked each other, but they got into arguments all the time. one day they were arguing again and they were on the other side of the island when finally Selena kissed Robert. Then she walked away. Robert went after her and grabbed her by the waist, scooped her up and kissed her. They sat on the beach together and watched the sunset. then Piper and Annabeth saw them together on the beach and they smiled to themsevles and gave Robert a ring made of pearls.
